Why augmented reality will be big in business first

THE history of computers is one of increasing intimacy. At first users rented time on mainframe machines they did not own. Next came the “personal computer”. Although PCs were confined to desks, ordinary people could afford to buy them, and filled them with all manner of personal information. These days smartphones go everywhere in their owners’ pockets, serving as everything from a diary to a camera to a voice-activated personal assistant.The next step, according to many technologists, is to move the computer from the pocket to the body itself. The idea is to build a pair of “smart glasses” that do everything a smartphone can, and more. A technology called “augmented reality” (AR) would paint computerised information directly on top of the wearers’ view of the world. Early versions of the technology already exist (see ). If it can be made to work as its advocates hope, AR could bring about a new and even more intimate way to interact with machines. In effect, it would turn reality itself into a gigantic computer screen.
